What's incredible weird is that one of the mini worked before I Store it, the other regular snes a Gpm-02 and the other mini didn't work, but all 3 give the same voltage drop?? Could it be the power brick? I mean on my rgb snes it works ok. 9v and 5v.. arrggg where is all your spare parts when you need them.. unfortunately I only have one snes power brick right now at my place, been thinking of just Soldering another 12v or 9v and test it oit

Well a bit of success, the consoles are good! yeih!... I wired my old power brick for the super famicom directly to the 7805 voltage regulator, all of them boot.. now wiring it to the solder points of the AC plug to see if it is actually the brick or something before the voltage regulator.

thanks for the info, I just tried the SFC power brick, which is a third party 9V and it worked also from the plug solder points, so going to open the super nintendo power brick and check what's going on or just go out and buy another one.

thanks all for your help!, is there a repair wiki for the snes like arcade otaku? so I can post my findings for future troubleshoot?

Update: - the culprit was the big capacitor on the power brick. When I opened it up it looked brand new.. I was getting ready to discharge it and found the solder joints cracked.. I took the oportunity to desolder it test it.. it was ok.. resolder it and boom everything is working now!

Funny thing is that my rgb snes didn't work on composite, and sound was humming with fade sound...which I though has to do maybe with the current, I didn't notice it before as I was just using rgb video while installing my retro setup (sound was finished yesterday).

Wondering why it did get 9v and 5v from the regulator and showed a perfect rgb image. Maybe motherboard revision had something to do?
